Umm...you tell me...
We weren't planning on pulling up the floor...BTW...there were 3 floors that needed to be pulled up. The top one wasn't too bad (only starting to rot from underneath). But the two underneath were totally rotted out.
What you are looking at (in the picture below) between the 2" x 4"s...is the ceiling of the downstairs (hallway...I think).
And this (below) is the part of the floor that cannot be ripped up (even though it really should be).
So...What do you think? How's the remodel going?
